When Vaughn was here last week I tried his easy rougher and sliced my fingers (not bad) wiping off the dust etc, from the cutter. Then I realized I was planting my DNA in his foam handle with my blood.
I like my hand held hollowing tool made by Jeff Nicol and thought I have to get some carbide on there. Jeff sent me a round tip and a square one too, made from old saw blade, but I have not come up with a good jig to sharpen them. Yes, I have the mini monster but I still like using this tool to smooth out HF's.
I adapted it with just a small washer under the cutter and used the screw that came with my rig (larger diameter) and tightened her down. $18 +tax.
Cheap and easy carbide finisher!
